It is manufactured from M2 high speed steel with a purple\/bronze coating and features a web-thinned, tapered web design for reduced thrust and cleaner entry. The straight-cylindrical shank and right-hand spiral fluting make it compatible with standard drill chucks. At 5.125 inches overall length with a 3.75-inch flute, this bit is suited for through-hole and deeper drilling work across a range of metal workpiece materials. Licensed tradespeople and machinists reach for this bit in everyday production and maintenance drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is designed for drilling steel, stainless steel, cast iron, superalloys, and titanium. It carries ANSI specification designation and falls within the HX10-HX15-HX18 series, which covers general-purpose jobber-length tooling. Typical applications include structural fabrication shops, maintenance facilities, and field service environments where a reliable letter-size drill is required. The 135-degree point geometry reduces walking on hard materials and lowers the need for a center punch on flat stock. Coolant-through is not supported on this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter W size — 0.386 inches decimal diameter for precise letter-series hole requirements\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip with web thinning reduces thrust and minimizes walking\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction handles steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003ePurple\/bronze coating provides surface hardness and lubricity for extended tool life in metal drilling\u003c\/li\u003e\n\u003cli\u003eRegular spiral fluting with tapered web maintains chip evacuation through a 3.75-inch flute length\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit within the PRECISION TWIST DRILL HX10-HX15-HX18 series.
